RPC Containers

Europe's leading rigid plastics packaging manufacturer, RPC Containers, is on track to achieve its 40% energy saving target on generating chilled process water at its Corby site thanks to our intelligent cooling solution. We retro-fitted a TC500 free-cooling system to their Montair chiller plant in August 2008: it has already cut the annual running cost by 45% and will have paid for itself by October 2010.

Ian Renshaw, Operations Manager at the Corby site explains why we were chosen for the project: "IsoCool has an excellent reputation. They listened carefully to what we needed and developed an excellent solution at a competitive price."

The TC500 system we installed uses a 400kW dry air blast cooler with a plate heat exchanger for frost protection to provide a cooling source when the ambient will allow partial and up to 100% direct air cooling, offloading the chillers. The lower the ambient conditions, the more effective the TC500 becomes, culminating in the compressors and the fans being switched off by the IsoCool intelligent control system.

Ian Renshaw explains: "Below 18°C we operate on partial free cooling, however the chillers switch off below 12°C. Last winter we were able to switch the chillers off completely, and from September we’ve been running on partial free cooling."

He adds: "The installation was seamless - we didn't even have to shut the plant down. IsoCool is now working at other sites in the RPC Group and I would recommend them to any manufacturer that is looking to reduce its energy consumption and cut costs. We monitored the data pre and post installation and the results speak for themselves; the return on investment is fantastic."
